I recently bought a intake tube and an upper and lower box. I have a 2006 IS350. The intake tube does not fit onto the car and one of the pipes does not insert into the stock intake tube. I need some suggestions on what to do. I was thinking about buying an fsport intake and returning everything else. I need to pass smog soon and I have an injen which isnt CARB certified. Please let me know of any suggestions.
Also, is there a different tube for the 4-cylinder IS250 and 6-cylinder IS350? I think there is because this one doesnt fit onto my 350.
I think your issue is that you're missing the adapter that retrofits the stock intake tube to the aftermarket one similar to the piece all the way on the left side of the end of the tube in this picture.
